  var q = "$name VARCHAR";
  if (maxLength != null) {
    q += "($maxLength)";
  }
  if (unique) {
    q += " UNIQUE";
  }
  if (!nullable) {
    q += " NOT NULL";
  }
  if (defaultValue != null) {
    q += " DEFAULT $defaultValue";
  }
  if (check != null) {
    q += " CHECK($check)";
  }
  _columns.add(q);
  _columnsData.add(DbColumn(

      unique: unique,
